Abstract

A method of processing signals received from an electronic device ( 106, 202 ) in a cellular network ( 100, 200 ) that utilizes variable rate vocoding comprising receiving a first series of low rate frames ( 318 ) at the cellular network; receiving a high rate frame ( 320 ) that has at least one bit error at the cellular network after receiving the first series of low rate frames, wherein the rate of the high rate frame can be determined; and sending a request ( 310 ) to the electronic device to retransmit the high rate frame.

 sending a first series of low rate frames to the cellular network; 
 sending a first high rate frame to the cellular network after sending the first series of low rate frames, wherein the rate of the first high rate frame can be determined by the cellular network and wherein the first high rate frame can not be decoded by the cellular network; and 
 receiving a request from the cellular network to transmit a second high rate frame, wherein the second high rate frame is a control frame and wherein the request from the cellular network is in response to the first high rate frame not being able to be decoded by the cellular network. 
 
     
     
       8. The method of  claim 7  wherein the cellular network utilizes a rate determination algorithm to determine the rate of the high rate frame.

       10. The method of  claim 9  wherein the request received by the electronic device to transmit the second high rate frame includes a Pilot Measurement Request Order. 
     
     
       11. The method of  claim 10  wherein the first high rate frame includes a Pilot Strength Measurement Message.

 a rate determination module adapted to determine a rate of the high rate frame; and 
 a rate monitoring module adapted to initiate sending a request for transmission of a high rate frame to an electronic device. 
 
     
     
       15. The RAN of  claim 14  wherein the high rate frame includes a Pilot Strength Measurement Message. 
     
     
       16. The method of  claim 15  wherein the request to the electronic device for transmission of the high rate frame includes a Pilot Measurement Request Order.
